Can I request an immediate offset through eServices for both demanded overpayments and voluntary refunds?

Answer
No. Voluntary refunds via immediate offset are not allowed by the Centers for Medicare & Medicaid Services (CMS) and are not available through the eOffset feature in eServices. You may only submit an eOffset request once you have received a demand letter or invoice for the overpayment. 

If you wish to submit a voluntary refund, you may use our eCheck feature to conveniently resolve your overpayment via a secure electronic payment transaction. When submitting your payment, simply indicate on the eCheck form that your payment is not associated with a demand letter and upload a copy of your voluntary refund form and documentation. The eCheck feature is easily accessible from the Financial Tools tab.
